A compressed air energy storage system with variable pressure ratio
Since the pressure in the air storage device is low in the initial energy storage, the high-pressure air discharged from the compressor enters the air storage device and diffuses rapidly, which wastes a certain amount of pressure energy. That is to say, the compressor can be adjusted to discharge low-pressure air in the initial energy

Thermal energy storage
Thermal energy storage ( TES) is the storage of thermal energy for later reuse. Employing widely different technologies, it allows surplus thermal energy to be stored for hours, days, or months. Scale both of storage and use vary from small to large – from individual processes to district, town, or region.
PUMPED STORAGE HYDROPOWER – HELPING TO DRIVE THE
Water batteries, or pumped storage hydropower, currently store over 95% of the world''s electricity. Traditionally, pumped storage had been used to take advantage of excess electricity produced by nuclear and fossil-fuel based plants in the middle of the night when most people are asleep. Now, it is being eyed as a sustainable solution for the
